I'm in my 20s and recently started having sex. whenever I'm on top it feels like I have to pee. (I have actually gotten up to pee, but when I come back it still feels like I need to) Will this go away? as in I just have to get used to it/wait it out? and does this happen to other people?

Yeah, also... some people claim the feeling of hitting the G spot can feel like you have to pee, I dunno?
Also, some positions seem to make him hit my bladder more or something and Ill feel like I have to pee. I usually just adjust my hips or the angle and it makes it feel better.
